Hippolyta

Hippolyta (died 1247 BC) is a figure in Greek mythology who was said to have been a queen of the Amazons and the sister of Penthesilea. She was an enemy of King Theseus of Athens, and she died in battle with him; she was either killed by Hera (disguised as an Amazon), or was accidentally killed by a javelin thrown by Penthesilea while freeing her from Theseus' troops.

Biography
A queen of the Amazons, a tribe of warrior women descended from Ares, Hippolyta was kidnapped by Theseus, triggering a war with Athens. Although Hippolyta bore a son to Theseus, he lost interest in her and she eventually returned to the lands of the Amazons. She then encountered Heracles, sent to retrieve the belt of Ares from her as one of his twelve quests. She gave the belt to him willingly, but this angered the goddess Hera. Disguised as an Amazon she incited the women to attack Heracles, who killed Hippolyta in his haste to exit their dangerous land.
